TOMOGRAPHIC IMAGE-CAPTURING TECHNIQUE

摘要

A tomographic image-capturing technique is described. According to one device aspect (100) of the technique, a radiation source (102) is embodied to emit a beam. The radiation source (102) has a first transverse dimension (108) across the beam and a second transverse dimension (110) substantially perpendicular to the first transverse dimension (108). The second transverse dimension (110) is larger than the first transverse dimension (108). A detector (106) is embodied to capture the beam. A sample holder (104) arranged between radiation source (102) and detector (106) is embodied to rotate a sample in the beam about a first axis (112) and about a second axis (114) which differs from the first axis (112).
